To all 'whom it may concern:

Be t known that we. JOHN POLACHEK, JULI s JErsnN, andEDMUNp Pennini. citizensI of the United4 States, and'residents respectively, of the city of" New York, borough of Manhattan. in the county and State of New York, of the. city of New York. borough ofl Brklyn, in the county of Kibgs and State of New York. und of the city of New York, Elmhurst Manor, Long I and, borough of Queens, in the county of ueens and State of New York. have in'- vented a. new and Improved lVindow, of which the following is e full, clear, and exact description'. A

This invention relates to improvements in windows and has particular reference to a metallic window construction.

An object of the invention is to provide an improved window wherein thef'window frame and sashee are so constructed and interengaged that the same will effectively prevent the ingress of; air and dust into a room when the sashes are in closing position.

Another object is the provision of an improved window in which the frame and sashes are so assembledthat any rattling of the sas'hes, due to lateral movement thereof with respect to the fra/ine, will be. prevented.

A further object is to so construct the trames and sashes that the window may be readily and' quickly assembled in operative position.

The above and other objects will appear more clearly from the .following detail description, when taken in connection with the accompanying drawings. which illustrate a preferred embodiment of the inventive idea..

In the drawings- Figure 1 is a front elevation of the window constructed in accordance with the in vention;

Figure 2 is a fragmentary transverse section of the window showing both sashes in cross section;

Figure 3 is a vertical sectional view of the window with both sashes in closing position; and

Figure 4 is aperspective vicw ot' one of the stiles of the sashes.

The window is made of any desired mav terial, such as steel or bronze, which is rolled or extruded to form the various parts of the window. The frame of the window comprises the side, top and' sillsections 5, 6 and 7 respectively. Inasmuch as the side and top sections are identical in construction, a description of one will suilice for both and similar characters will be used to designate like parts. The side sections, only one of which is illustrated in Figure 2, each comprises the outer, intermediate and inner portions 8, 9 and 10, respectively, the intermediate portion being secured along its longitudinal edges with the adjacent overlapping longitudinal edges of the Outer and inner sect-ions by means of suitable .fasteners 11. Forming n part of the inner portion 10 is a stile 12 secured to said portion y by means of fasteners 13; Medially of its longitudinal edges the intermediate portion 9 is bent to provide a, parting strip 14 and on opposite sides of said parting strip the portion 9 is further 'provided with flanges l5 which'combine with the sides of the parting strip to form grooves 16 for a purpose which will presently appear. The sides of the parting strip 14 are also formed with vertically disposed grooves 17 similar to grooves 18 formed inopposed surfaces of the portion 8 and the stile 12.

The sill section 7 is of channeled formation so as to receive a suitable material 19 utilized to securely anchor said section in l proper position with respect to the sill ol the window opening. Intermediate the edges of the Vsection 7 the same is provided with an upwardly projecting portion `2() having the sides 21 and 22, the former of which cooperates with e flange 23 tol forni e groove 24 for e purpose which will appear in the course of the description.

The Window further comprises the upper and lower sashes 25 and 26 which are practically' identical in construction. The sashes'25 and 26 include Stiles, generally indicated by the numeral 27, the upper and lower rails 28 and 29 and the meeting rails 30 and 31. The stiles 27 and the upper and lower rails 28 and 29 are substantially alike in construction and each includes a. web ortion 32 having the flanges 33 exten ing trom the longitudinal edges thereof in the seme direction and in parallel relation.

'S2-9 of the lower sash are Formed integrally with one of the flanges 33 and extending from the inner face thereot and intermediate its longitudinal'ed es is a diagonally disposed flange 34 which combines with the outer portion of said flange 33 to form a substantially V-shaped groove The grooves 35 of the various stiles 27 and upper rail 2S are designed to receive the flanges 15 of the intermediate portions of the side and top sections'of the frame, the outer portions ofthe flanges 33 upon which the flanges 34 are formed then engaging in the grooves 1G, thus forming a. connection between the sashes and frame, which will prevent lateral movement and consequent rattling ot' the sashes. The outer surfaces of the last named flanges 33 of the Stiles 27 and' upper rail 28 engage thc sides of the parting strip 14 and combine with thegrooves 17 therein to forni small air chambers which aid in preventing lair passing-around the sashes int-o the interior of a room. This passage of the air is further prcvented by the plurality of points of 'contact between the flanges 15, 33 and 34.v

ln addition to the air chambers formed by the grooves 18 the outer flanges of the stiles 27 and upper rail 28 combine with the grooves 18 in the members 8 and 12 to form other air chambers. Also the stiles Q7 and upper rail 28 combine with the sections 5 and of the frame to form the large airchambcrs 36. Adjacent one`ofthe longitudinal edges of the web portion 32 of each stile and upper rail another flange Ill', extends in the opposite direction trom the 4flanges 33 but in arallel relation thereto'and this flange 3'( is utilized in securing the pane of glass in the window sash, as clearly illustrated in Figures 2 and 3.

The flanges 38 and 39 of the lower rail of different widths and the fla-nge 38 is provided with a flange 40 similar to the flanges 34 to form a groove for receiving the flange 23 when the lower sash is in closing position, The flange 40 then also engages in the groove 24 to form a joint between the lower rail and sill similar to that described in connection with the stiles 27 and upper rail 28. The inner lflange 39 of the lower rail overlaps thc side :22 of the portion and said lower rail combines with the sill section to form the air chamber 41 similar to the chambers 36.

The meeting rails 30 and 31 are provided, respectively, along their adjacent edges with flanges 42 and 43 which overlap and interengage, as illustrated in Figure 3, when the sashes are in closing position. Disposed on each side of the window and extending partially over the top thereof are the casings 44, in which the parting strips 45 are disposed for dividing the casings into compartments for receiving the usual coun- -formed with a parting terweights 47 for the sashes. The intermediate portions 9 of the side sections of the frame may be provided, if desired, with rubber bumpers 48 supported by means of plates 49 and against which the lower sash may engage to prevent noise when opening the window. The intermediate portions 9 may be displaced, by removing the screws 11, whereby access may be had to the interior of the casings 44 to repair or replace parts therein. The lower sash 26 may be provided with an operating handle 50 to facilitate the raising and .lowering of the sash. The meeting rails 30 and 31 are locked together by a locking device 51 of any desired construction. The outer portions 8 of the side sections may have anchored therein the rings 52 utilized for the purpose of attaching a safety b 'elt'thercto when washing the windoi lVhat is claimed is:
